The moon is 384,000 km from the earth and makes 1 revolution in 27.3 days. Find its angular and linear speeds in its orbit.

    angular speed = 2 pi radians/27.3 days

    linear speed = (orbit circumference)/(27.3 days)

    They may want you to convert to radians and km per second. To do that, divide by the number of seconds in 27.3 days
